Barclays ePDQ Payment Gateway

Hello all!

Today we will be talking about Barclays online payment gateway valled ePDQ.
You can take a look at what they have got to say by clicking here to view Barclays’ site or you could keep reading 🙂
Well, for all you php guys out there, this post if for you!

Barclays ePDQ encrypts your data string of products in your basket and returns a result that is sent with your HTML form on your site.

<?php

$url = 'https://secure2.epdq.co.uk/cgi-bin/CcxBarclaysEpdqEncTool.e';
$params = "clientid=myclientid&amp;password=mypassword&amp;oid=4&amp;chargetype=Auth&amp;total=100&amp;currencycode=826";
$user_agent = "Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)";
$ch = curl_init();
curl_setopt($ch, CURLOPT_POST,1);
curl_setopt($ch, CURLOPT_POSTFIELDS,$params);
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 2);
curl_setopt($ch, CURLOPT_USERAGENT, $user_agent);
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE); // this line makes it work under https
$result=curl_exec($ch);
curl_close($ch);
<form action="https://secure2.epdq.co.uk/cgi-bin/CcxBarclaysEpdq.e" method="POST"><!--?php print "$result"; ?-->

<input name="returnurl" type="hidden" value="http://www.store.co.uk/" /> <input name="merchantdisplayname" type="hidden" value="My Store" /> <input type="submit" value="purchase" />

</form>

As you can see, it all seems quite easy.
You send through your data and it encodes it to look like something like this:


<form action="https://secure2.epdq.co.uk/cgi-bin/CcxBarclaysEpdq.e" method="POST"><input name="epdqdata" type="hidden" value="B5C14CFDF42DE6F1F3EE38CA469E4345927CFD45C2191AEBA3CB93A004679724369A7F64F5B0E991A 79C39EA37A8727C3BE49ADF13556356021E5EBB361089F0" /> <input name="returnurl" type="hidden" value="http://www.store.co.uk/" /> <input name="merchantdisplayname" type="hidden" value="My Store" /> <input type="submit" value="purchase" /></form>

Remember to read the following documents, they are very useful in troubleshooting:

http://www.barclaycard.co.uk/business/documents/pdfs/user_guideV5.0.pdf

Here are some sample scripts from Barclays themselves:

Hope that helped someone!

I am getting the following error when trying to use Jersey as delivery country.It works for all others.Doesnt ePDQ support this country?
Any body has encountered this ?

“Sorry, there has been a problem processing your payment.
Billing Country is invalid, received JE.”

How do I get this to work ? Where is the value coming from, can the user input a total or is it based on something else?

Hi,

This is the bit I’m stuck on. When I submit the form is says ‘Mandatory information not present.’.

$params = clientid=myclientid&password=mypassword&oid=4&chargetype=Auth&total=100&currencycode=826?;

The above is from your post and is the same as the CURL script from Barclays. Can you explain how I enter my details as the parameters? Where it says clientid=myclientid, do I just change ‘myclientid’ for the 5 digit client id? same with mypassword, do I put the passphrase entered during the admin set up? oid=4? do I change this, it’s not madatory, so can I delete it? the total=100 surely has to change to maybe $cartTotal?

Please help! It seems easy but there are loads of people over the net asking for help. I’ve found this post very helpful. I was using the php encryption and have changed to use the CURL encryption.

Hi,
I have a website that has a one page form that collects simple customer details to pay for a booking on a holiday home. I have the website working well but need to integrate Barclays ePDQ. I have sat and read the integration document over several times and am now stuck. I have never really used Perl or PHP so have installed the scripts given by Barclays to do the server side bit.
This is the link given to the help document but (ww.barclaycard.co.uk/business/activate-epdq-cpi)I am not really sure on how the encryption bit works.
Is anyone out there willing to help do a “walkthrough”? I cant imagine its too difficult if you know what your doing.
Thanks in anticipation…
Jo
